Bluefin is a cloud-native desktop operating system that reimagines the Linux desktop experience for modern computing environments.
For end users, it provides a system as reliable as a Chromebook with near-zero maintenance. For developers, it offers a kickass cloud-native developer workflow with integrated container tools, declarative system management, and seamless CI/CD integration. Check Introduction to Bluefin for a feature walkthrough.

Secure Boot
Secure Boot is supported by default on our systems, providing an additional layer of security. After the first installation, you will be prompted to enroll the secure boot key in the BIOS.
Enter the password universalblue
when prompted to enroll our key.
If this step is not completed during the initial setup, you can manually enroll the key by running the following command in the terminal:

Secure boot is supported with our custom key. The pub key can be found in the root of the akmods repository here. If you'd like to enroll this key prior to installation or rebase, download the key and run the following:
sudo mokutil --timeout -1
sudo mokutil --import public_key.der
